The properties of amylose of cow pea starch were investigated. Amylose content of cow pea was 25.1 % and iodine binding capacity was 20.2 %. The β-amylolysis limit of the amylose was 82.3 %. The limiting viscosity number of. the amylose fraction was 204 ㎖/g and the corresponding average degree of polymerization was 1,510 glucose units. The percent distribution of molecular weight of the amylose by gel chromatography was $lt;l×10⁴(0.7 %), 1×10⁴%), 4×10⁴∼5×10^5(44.6%), 5×10^5∼4×10^7 (49.6 %).
